Power Tool Safety Rules

Read and understand all instructions. Failure to follow all instructions listed below, may

result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

WARNING

Work Area

Keep your work area clean and well lit. Cluttered

benches and dark areas invite accidents.

Do not operate power tools in explosive atmospheres,

such as in the presence of flammable liquids, gases,

or dust. Power tools create sparks which may ignite the

dust or fumes.

Keep by-standers, children, and visitors away while

operating a power tool. Distractions can cause you to

lose control.

Electrical Safety

Double Insulated tools are equipped with a polarized

plug (one blade is wider than the other.) This plug

will fit in a polarized outlet only one way. If the plug

does not fit fully in the outlet, reverse the plug. If it

still does not fit, contact a qualified electrician to

install a polarized outlet. Do not change the plug in

any way. Double Insulation eliminates the need for

the three wire grounded power cord and grounded

power supply system. Before plugging in the tool, be

certain the outlet voltage supplied is within the voltage

marked on the nameplate. Do not use “AC only” rated

tools with a DC power supply.

Avoid body contact with grounded surfaces such as

pipes, radiators, ranges and refrigerators. There is an

increased risk of electric shock if your body is

grounded. If operating the power tool in damp locations

is unavoidable, a Ground Fault Circuit Interrupter must

be used to supply the power to your tool. Electrician’s

rubber gloves and footwear will further enhance your

personal safety.

Don't expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of

electric shock.

Do not abuse the cord. Never use the cord to carry the

tools or pull the plug from an outlet. Keep cord away

from heat, oil, sharp edges or moving parts. Replace

damaged cords immediately. Damaged cords increase

the risk of electric shock.

When operating a power tool outside, use an outdoor

extension cord marked "W-A" or "W." These cords are

rated for outdoor use and reduce the risk of electric

shock. Refer to “Recommended sizes of Extension

Cords” in the Accessory section of this manual.

Personal Safety

Stay alert, watch what you are doing and use common

sense when operating a power tool. Do not use tool

while tired or under the influence of drugs, alcohol, or

medication. A moment of inattention while operating

power tools may result in serious personal injury.

Dress properly. Do not wear loose clothing or jewelry.

Contain long hair. Keep your hair, clothing, and gloves

away from moving parts. Loose clothes, jewelry, or

long hair can be caught in moving parts. Keep handles

dry, clean and free from oil and grease.

Avoid accidental starting. Be sure switch is “OFF”

before plugging in. Carrying tools with your finger on

the switch or plugging in tools that have the switch

“ON” invites accidents.

Remove adjusting keys or wrenches before turning the

tool “ON”. A wrench or a key that is left attached to a

rotating part of the tool may result in personal injury.

Do not overreach. Keep proper footing and balance at

all times. Proper footing and balance enables better

control of the tool in unexpected situations.

Use safety equipment. Always wear eye protection.

Dust mask, non-skid safety shoes, hard hat, or hearing

protection must be used for appropriate conditions.

Tool Use and Care

Use clamps or other practical way to secure and

support the workpiece to a stable platform. Holding

the work by hand or against your body is unstable and

may lead to loss of control.

Do not force tool. Use the correct tool for your

application. The correct tool will do the job better and

safer at the rate for which it is designed.

Do not use tool if switch does not turn it “ON” or

“OFF”. Any tool that cannot be controlled with the

switch is dangerous and must be repaired.

Disconnect the plug from the power source before

making any adjustments, changing accessories, or

storing the tool. Such preventive safety measures

reduce the risk of starting the tool accidentally.

Store idle tools out of reach of children and other

untrained persons. Tools are dangerous in the hands of

untrained users.

Maintain tools with care. Keep cutting tools sharp and

clean. Properly maintained tools, with sharp cutting

edges are less likely to bind and are easier to control.

Any alteration or modification is a misuse and may

result in a dangerous condition.

Check for misalignment or binding of moving parts,

breakage of parts, and any other condition that may

affect the tools operation. If damaged, have the tool

serviced before using. Many accidents are caused by

poorly maintained tools. Develop a periodic

maintenance schedule for your tool.

DM 2610916195 4/03 4/28/03 10:52 AM Page 2

Page 3

Use only accessories that are recommended by the

manufacturer for your model. Accessories that may

be suitable for one tool, may become hazardous

when used on another tool.

Service

Tool service must be performed only by qualified

repair personnel. Service or maintenance performed by

unqualified personnel could result in a risk of injury. For

example: internal wires may be misplaced or pinched,

safety guard return springs may be improperly

mounted.

When servicing a tool, use only identical replacement

parts. Follow instructions in the Maintenance section

of this manual. Use of unauthorized parts or failure to

follow Maintenance Instructions may create a risk of

electric shock or injury. Certain cleaning agents such as

gasoline, carbon tetrachloride, ammonia, etc. may

damage plastic parts.

Accessories must be rated for at least the speed

recommended on the tool warning label. Wheels

and other accessories running over rated speed can

fly apart and cause injury.

Hold tool by insulated gripping surfaces when

performing an operation where the cutting tool may

contact hidden wiring or its own cord. Contact with

a "live" wire will make exposed metal parts of the tool

"live" and shock the operator. If cutting into existing

walls or other blind areas where electrical wiring may

exist is unavoidable, disconnect all fuses or circuit

breakers feeding this worksite.

Do not operate the flexible shaft with a sharp bend.

Over bending the shaft can generate excessive heat

on the jacket or hand piece. The recommended

minimum is 6" radius.

Always disconnect the power cord from the power

source before making any adjustments or attaching

any accessories. You may unexpectedly cause the

tool to start leading to serious personal injury.

Be aware of the switch location, when placing the

tool down or when picking the tool up. You may

accidentally activate the switch.

Always hold the hand piece firmly in your hands

during the start-up. The reaction torque of the motor,

as it accelerates to full speed, can cause the shaft to

twist.

Always wear safety goggles and dust mask. Use

only in well ventilated area. Using personal safety

devices and working in safe environment reduces risk

of injury.

After changing the bits or making any adjustments,

make sure the collet nut and any other adjustment

devices are securely tightened. Loose adjustment

device can unexpectedly shift, causing loss of control,

loose rotating components will be violently thrown.

Do not reach in the area of the spinning bit. The

proximity of the spinning bit to your hand may not

always be obvious.

Allow brushes to run at operating speed for at least

one minute before using wheel. During this time no

one is to stand in front or in line with the brush.

Loose bristles or wires will be discharged during the

run-in time.

Wire and bristle brushes must never be operated at

speeds greater than 15,000/min. Direct the

discharge of the spinning wire brush away from

you. Small particles and tiny wire fragments may be

discharged at high velocity during the “cleaning”

action with these brushes and may become imbedded

in your skin. Bristles or wires will be discharged from

the brush at high speeds.

Wear protective gloves and face shield with wire or

bristle brushes. Apply wire or bristle brushes lightly

to the work as only the tips of the wire/bristles do

the work. “Heavy” pressure on bristles will cause the

wire or bristle to become overstressed, resulting in a

wiping action and will cause the bristles/wire to be

discharged.

Carefully handle both the tool and individual

grinding wheels to avoid chipping or cracking.

Install a new wheel if tool is dropped while

grinding. Do not use a wheel that may be damaged.

Fragments from a wheel that bursts during operation

will fly away at great velocity possibly striking you or

bystanders.

Never use dull or damaged bits. Sharp bits must be

handled with care. Damaged bits can snap during

use. Dull bits require more force to push the tool,

possibly causing the bit to break.

Use clamps to support workpiece whenever

practical. Never hold a small workpiece in one hand

and the tool in the other hand while in use. Allow

for sufficient space, at least 6", between your hand

and the spinning bit. Round material such as dowel

rods, pipes or tubing have a tendency to roll while

being cut, and may cause the bit to “bite” or jump

toward you. Clamping a small workpiece allows you

to use both hands to control the tool.

Safety Rules for Rotary Tools

DM 2610916195 4/03 4/28/03 10:52 AM Page 3

Page 4

Inspect your workpiece before cutting. When cutting

irregularly shaped workpieces, plan your work so it

will not slip and pinch the bit and be torn from your

hand. For example, if carving wood, make sure there

are no nails or foreign objects in the workpiece. Nails

or foreign objects can cause the bit to jump.

Never start the tool when the bit is engaged in the

material. The bit cutting edge may grab the material

causing loss of control of the cutter.

Avoid bouncing and snagging the wheel, especially

when working corners, sharp edges etc. This can

cause loss of control and kick-back.

The direction of feed with the bit into the material

when carving, routing or cutting is very important.

Always feed the bit into the material in the same

direction as the cutting edge is exiting from the

material (which is the same direction as the chips

are thrown). Feeding the tool in the wrong direction,

causes the cutting edge of the bit to climb out of the

work and pull the tool in the direction of this feed.

If the workpiece or bit becomes jammed or bogged

down, turn the tool “OFF” by the switch. Wait for

all moving parts to stop and unplug the tool, then

work to free the jammed material. If the switch to

the tool is left “ON” the tool could restart

unexpectedly causing serious personal injury.

Do not leave a running tool unattended, turn power

off. Only when tool comes to a complete stop it is

safe to put it down.

Do not grind or sand near flammable materials.

Sparks from the wheel could ignite these materials.

Do not touch the bit or collet after use. After use the

bit and collet are too hot to be touched by bare hands.

Regularly clean the tool's air vents by compressed

air. Excessive accumulation of powdered metal inside

the motor housing may cause electrical failures.

Do not allow familiarity gained from frequent use of

your rotary tool to become commonplace. Always

remember that a careless fraction of a second is

sufficient to inflict severe injury.

Do not alter or misuse tool. Any alteration or

modification is a misuse and may result in serious

personal injury.

This product is not intended for use as a dental

drill, in human or veterinary medical applications.

Serious personal injury may result.

When using the steel saws, cutoff wheels, high

speed cutters or tungsten carbide cutters, always

have the work securely clamped. Never attempt to

hold the work with one hand while using any of

these accessories. The reason is that these wheels

will grab if they become slightly canted in the groove,

and can kickback causing loss of control resulting in

serious injury. Your second hand should be used to

steady and guide the hand holding the tool. When a

cutoff wheel grabs, the wheel itself usually breaks.

When the steel saw, high speed cutters or tungsten

carbide cutter grab, it may jump from the groove and

you could lose control of the tool.

Some dust created by power

sanding, sawing, grinding,

drilling, and other construction activities contains

chemicals known to cause cancer, birth defects or

other reproductive harm. Some examples of these

chemicals are:

• Lead from lead-based paints,

• Crystalline silica from bricks and cement and other

masonry products, and

• Arsenic and chromium from chemically treated

lumber.

Your risk from these exposures varies, depending on

how often you do this type of work. To reduce your

exposure to these chemicals: work in a well ventilated

area, and work with approved safety equipment, such

as those dust masks that are specially designed to

filter out microscopic particles.

COLLET NUT — To loosen, first press shaft lock

button and rotate the shaft by hand until the lock

engages the shaft preventing further rotation.

Do not engage lock while the

Rotary Tool is running.

With the shaft lock engaged use the collet wrench to

loosen the collet nut if necessary. The collet nut must

be loosely threaded on when inserting an accessory.

Change accessories by inserting the new one into the

collet as far as possible to minimize runout and

unbalance. With the shaft lock engaged, finger tighten

the collet nut until the accessory shank is gripped by

the collet. Avoid excessive tightening of the collet

nut when there is no bit inserted.

COLLETS — Four different size collets (see illus-

tration), to accommodate different shank sizes, are

available for your Rotary Tool. To install a different

collet, remove the collet nut and remove the old collet.

Insert the unslotted end of the collet in the hole in the

end of the tool shaft. Replace collet nut on the shaft.

Always use the collet which

matches the shank size of the

accessory you plan to use. Never force a larger

diameter shank into a collet.

Note: Some rotary tool kits may not include all four

collets sizes.

BALANCING ACCESSORIES — For precision work, it

is important that all accessories be in good balance

(much the same as the tires on your automobile). To

true up or balance an accessory, slightly loosen collet

nut and give the accessory or collet a 1/4 turn. Re-

tighten collet nut and run the Rotary Tool. You should

be able to tell by the sound and feel if your accessory

is running in balance. Continue adjusting in this

fashion until best balance is achieved. To maintain

balance on abrasive wheel points, before each use,

with the wheel point secured in the collet, turn on the

Rotary Tool and run the 415 Dressing Stone lightly

against the revolving wheel point. This removes high

spots and trues up the wheel point for good balance.

The hanger is provided for the use of hanging your

tool while using the flex-shaft or for storage. If you do

not use the hanger, remove it from the tool and snap

it back into place underneath the cord so it will be out

of the way while the tool is in use.

DREMEL KEYLESS CHUCK

Use only with black chuck

#4486. Other chucks may not

allow accessory bit to be tightened fully.

The keyless chuck holds various accessories with

shank sizes 1/32" to 1/8" and is intended for light duty

accessories such as drill bits, sanding drums,

polishing accessories, wire and bristle brushes and

cut-off wheels. The keyless chuck allows you to

change accessories frequently, quickly and easily.

There are some applications which can generate high

forces on the bit or if you are unable to generate

finger tightening pressure sufficient to secure the bit

you must use the supplied wrench to assist in

securing the bit.

Attaching the Keyless Chuck and Accessory Bit

Read and understand the

manual for use of the keyless

chuck with the tool. Insert and securely tighten the

shank of the accessory well within the jaws of the

chuck. If an accessory is not properly gripped within

The Rotary Tool is a handful of high-speed power. It

serves as a carver, grinder, polisher, sander, cutter,

power brush, drill and more.

The Rotary Tool has a small, powerful electric

universal motor, is comfortable in the hand, and is

made to accept a large variety of accessories

including abrasive wheels, drill bits, wire brushes,

polishers, engraving cutters, router bits, cutting

wheels and attachments. Accessories come in a

variety of shapes and permit you to do a number of

different jobs. As you become familiar with the range

of accessories and their uses, you will learn just how

versatile the Rotary Tool is. You’ll see dozens of uses

you hadn’t thought of before.

The real secret of the Rotary Tool is its speed. To

understand the advantages of its high speed, you

have to know that the standard portable electric drill

runs at speeds up to 2,800 revolutions per minute.

The Rotary Tool operates at speeds up to 35,000

revolutions per minute. The typical electric drill is a

low-speed, high torque tool; the Rotary Tool is just

the opposite – a high-speed, low torque tool. The

major difference to the user is that in the high speed

tools, the speed combined with the accessory

mounted in the collet does the work. You don’t apply

pressure to the tool, but simply hold and guide it. In

the low speed tools, you not only guide the tool, but

also apply pressure to it, as you do, for example,

when drilling a hole.

It is this high speed, along with its compact size and

wide variety of special accessories and attachments,

that makes the Rotary Tool different from other tools.

The speed enables it to do jobs low speed tools

cannot do, such as cutting hardened steel, engraving

glass, etc.

Getting the most out of your Rotary Tool is a matter of

learning how to let this speed work for you. To learn

about more uses and the versatility of Dremel

accessories and attachments refer to this Owner's

Manual or Dremel's “Getting Started” booklet.

the jaws of a chuck it may loosen and fly out during

use possibly striking you or bystanders.

To replace or attach the keyless chuck accessory to

your MultiPro rotary tool, unplug the tool and engage

the shaft lock button then remove the collet and collet

nut. Thread the keyless chuck on the end of the shaft.

Engage the shaft lock button again, insert the

accessory shank into the chuck and finger tighten

until the shank is secure.

For small size drill bits, close the chuck to the point

where the bit will just fit in; then tighten securely. This

helps center the bit in the keyless chuck correctly. In

some high force applications such as removing metal,

tile cutting or routing, the bit (tungsten carbide

cutters, high speed cutters, router bits or tile cutters)

and chuck will become hot if overloaded for extended

periods of time. Overloading the chuck may cause the

bit to loosen and slip. It is recommended that in these

types of applications that the bit be secured in the

chuck with the supplied wrench and work in intervals

to allow cooling of the bit and chuck. If the bit slips

the tool will begin to vibrate excessively, this is an

indication that you should shut the tool off, re-

position and tighten the bit then allow the tool to run

no-load for a few minutes to cool.

The chuck should be cleaned occasionally to keep it

functioning properly. Simply remove the chuck from

the tool and gently tap the tip of the chuck on a fat

surface to remove any loose debris. In some

applications the keyless chuck may tighten up during

use. If this occurs, gently loosen using the wrench

included in your rotary tool kit.

Using the Rotary Tool

The first step in learning to use the Rotary Tool is to

get the “feel” of it. Hold it in your hand and feel its

weight and balance. Feel the taper of the housing.

This taper permits the Rotary Tool to be grasped

much like a pen or pencil. The 395T6 Variable Speed

tool has a unique comfort grip on the nose and back

seating, which allows the user added comfort and

control during use. You can feel the difference!

Always hold the tool away from your face.

Accessories can be damaged during handling, and

can fly apart as they come up to speed. This is not

common, but it does happen.

Practice on scrap materials first to see how the

Rotary Tool's high speed action performs. Keep in

mind that the work is done by the speed of the tool

and by the accessory in the collet. You should not

lean on or push the tool during use.

Instead, lower the spinning accessory lightly to the

work and allow it to touch the point at which you want

cutting (or sanding or etching, etc.) to begin. Con-

centrate on guiding the tool over the work using very

little pressure from your hand. Allow the accessory to

do the work.

Usually, it is best to make a series of passes with the

tool rather than attempt to do all the work in one

pass. To make a cut, for example, pass the tool back

and forth over the work, much as you would a small

paint brush. Cut a little material on each pass until

you reach the desired depth. For most work, the

gentle touch is best. With it, you have the best

control, are less likely to make errors, and will get the

most efficient work out of the accessory.

For best control in close work, grip the Rotary Tool

like a pencil between your thumb and forefinger.

The “Golf Grip” method of holding the tool is used

for more aggressive operations such as grinding a

flat surface or using cutoff wheels.

WARNING

Wear Eye Protection

Whenever you hold the tool, be careful not to cover

the air vents with your hand. This blocks the air

flow and causes the motor to overheat.

Set the speed indicator to fit the job; to achieve the

best job results when working with different mate-

rials, the speed of the Rotary Tool should be regu-

lated. Only a full wave output speed control such as

the Dremel Model 221 should be used with the

275T6 Rotary Tool.

To select the right speed for each job, use a practice

piece of material. Vary speed to find the best speed

for the accessory you are using and the job to be

done.

NOTE: Speed is affected by voltage changes. A

reduced incoming voltage will slow the RPM of the

tool, especially at the lowest setting. If your tool

appears to be running slowly increase the speed

setting accordingly. The tool may not start at switch

position #1 in those areas where outlet voltage is

less than 120 volts. Simply move the switch lever to

a higher position to begin operation.

There are three basic types of Rotary Tools: single

speed, two-speed and variable speed models.

On the single speed model, there is an ON-OFF

switch. When the switch is on, the tool runs at 35,000

RPM.

On the two-speed model, there is a LO and HI switch.

When the switch indicator is on the low setting, the

tool runs at about 15,000 RPM. When the switch

indicator is on the high setting, the tool runs at about

35,000 RPM.

On the variable speed model, there are switch setting

indicators marked with a line. Slide to the number on

the housing to select the operating speed needed

from 5,000 – 35,000 RPM. You can refer to the

charts on page 24, 25, and 26 to determine the

proper speed, based on the material being worked

and the type of accessory being used. These charts

enable you to select both the correct accessory and

the optimum speed at a glance.

If you have a single-speed or two-speed model, you

will be able to use many accessories to do a wide

assortment of jobs. For the majority of applications,

all models of the Rotary Tool should be used at top

speed.

Needs for Slower Speeds

Certain materials, however, (some plastics and

precious metals, for example) require a relatively slow

speed because at high speed the friction of the

accessory generates heat and may cause damage to

the material.

Slow speeds (15,000 RPM or less) usually are best

for polishing operations employing the felt polishing

accessories. They may also be best for working on

delicate projects as “eggery” work, delicate wood

carving and fragile model parts. (All brushing

applications require lower speeds to avoid wire

discharge from the holder.) No greater than speed

setting 4 for the model 395-T6.

Higher speeds are better for carving, cutting, routing,

shaping, cutting dadoes or rabbets in wood.

Hardwoods, metals and glass require high speed

operation, and drilling should also be done at high

speeds.

The speed of Rotary Tool is controlled by setting

this indicator on the housing.

Assembly & Operation of Attachments

Flex-Shaft 225

Not for use with router bits. Use

with router bits will cause

kickback.

INSTALLATION INSTRUCTIONS

It is extremely important to carefully read and follow

the directions to assemble the flex-shaft to your

rotary tool below to ensure the tool will function

properly.

Attention: For optimum performance, allow your new

flex shaft attachment to run at high speed on your

rotary tool in a vertical position for 2 minutes before

use.

To properly attach the flex-shaft to the rotary tool,

THREE items must be removed from the tool: the

housing cap, collet nut and collet.

Step 1. Press the Shaft lock button, unscrew and

remove the collet nut.

If you need it, single-speed models also can have

speed control by using a Model 221 foot control unit.

Not for use with variable speed

or two speed models 285 or 395.

Use with external speed control will damage the

variable/two speed electronics.

The point to remember is this: You can do the great

majority of work with the single speed at its regular

speed of 35,000 RPM. But for certain materials and

types of work, you need slower speeds — which is the

reason the variable speed models and the speed

control units are available.

To aid you in determining the optimum operational

speed for different materials and different accessories,

we have constructed a series of tables that appear on

page 24, 25 and 26. By referring to these tables, you

can discover the recommended speeds for each type

of accessory. Look these tables over and become

familiar with them.

Ultimately, the best way to determine the correct speed

for work on any material is to practice for a few

minutes on a piece of scrap, even after referring to the

chart. You can quickly learn that a slower or faster

speed is more effective just by observing what happens

as you make a pass or two at different speeds. When

working with plastic, for example, start at a slow rate of

speed and increase the speed until you observe that the

plastic is melting at the point of contact. Then reduce

the speed slightly to get the optimum working speed.

Some rules of thumb in regard to speed:

1. Plastic and other materials that melt at low

temperatures should be cut at low speeds.

2. Polishing, buffing and cleaning with a wire brush

must be done at speeds not greater than 15,000

RPM to prevent damage to the brush.

3. Wood should be cut at high speed.

4. Iron or steel should be cut at high speed. If a high

speed steel cutter starts to chatter — this normally

means it is running too slow.

5. Aluminum, copper alloys, lead alloys, zinc alloys

and tin may be cut at various speeds, depending on

the type of cutting being done. Use paraffin or other

suitable lubricant on the cutter to prevent the cut

material from adhering to the cutter teeth.

Increasing the pressure on the tool is not the answer

when it is not performing as you think it should.

Perhaps you should be using a different accessory, and

perhaps an adjustment in speed would solve the

problem. Leaning on the tool does not help.

Let speed do the work!

WARNING

STEP 1

DM 2610916195 4/03 4/28/03 10:52 AM Page 12

Step 2. Unscrew the housing cap from the tool.

Step 3. Remove the collet.

Note: If the collet nut and collet are not removed from

the motor shaft, the tool will not function properly.

Step 4. Install the driver cap on the motor shaft and

tighten.

To prevent damage to tool, do

not overtighten driver cap.

Tighten the driver cap finger tight and then tighten an

additional 1/3 turn with the wrench. (Wrench included

with your rotary tool kit)

Step 5. Attach by screwing the collar of the flex-shaft

to the rotary tool. Make sure the square end of the

center core engages the square hole socket in the

driver cap.

Do not pull out center core to

engage into driver cap. This

could cause disengagement of center core from

handpiece. If tool stops when shaft is bent, center

core may be lodged in driver cap. Loosen shaft and

remove core from driver cap. Then screw flexible

shaft onto rotary tool housing again.

OPERATING INSTRUCTIONS

Disengagement of the Flex-Shaft

The flexible shaft may become disengaged if the

motor of your rotary tool is not elevated higher than

the working end of the flex-shaft. The #2222 Rotary

Tool Stand is recommended to hold the rotary tool at

the proper height.

Collet and Accessory Assembly

The collet assembly consists of a collet nut and collet.

Take the collet nut and collet that were removed from

your tool in step 2 and 3 and insert them into the tip

of the flex-shaft handpiece.

Insert an accessory or bit as deeply as possible to

avoid wobble during use. With the shaft lock button

engaged on the flex-shaft handpiece retighten the

collet nut.

Collet Removal and Replacement

Four different size collets to accommodate different

shank sizes, are sold separately for your flex-shaft. To

install a different collet, remove the collet nut and

remove the old collet. Insert the unslotted end of the

collet in the hole in the end of the flex-shaft. Replace

collet nut on the shaft. Always use the collet which

matches the shank size of the accessory you plan to

use. Never force a larger diameter shank into a collet.

FLEXIBLE SHAFT LUBRICATION — The flexible shaft

should be lubricated after every 25-30 hours of use.

To lubricate, unscrew the flexible shaft assembly from

the motor housing. Pull the center core out of the

flexible shaft assembly. Wipe a very thin film of a

good quality, high temperature grease on to the center

core.

To prevent damage to tool do not

over grease shaft. Too much

grease will cause the unit to overheat. Dremel shaft

lubricant No. 5990952 or automotive wheel bearing

grease should be used.

Reattach the flex-shaft to the rotary tool.

Grout Removal Kit 568

The #568 grout removal attachment comes

completely assembled and ready to use. Use the #569

(1/16") bit for tiles spaced more than 1/16" apart. If

your tiles are spaced more than 1/8" apart, it is

recommended that you use the #570 (1/8") bit.

Note: If the bit is too wide for the spacing between

your tiles, you may damage your tile or the grout

removal bit.

Step 1: Remove the housing cap from the tool.

Step 2: Insert the grout removal bit into your rotary

tool.

When inserting the #569 or #570

grout removal bit into your

Dremel rotary tool, be sure that the bit is secure

within the “jaws” of the collet. Use the wrench to

tighten the collet nut to prevent the bit from loosening

within the collet. Do not use your Dremel Chuck,

#4486, with the grout removal bits.

Step 3: Screw the grout removal attachment onto the

rotary tool.

Step 4: Adjust the attachment and bit to the desired

cutting depth.

Grout Removal Attachment Cutting Depth

Adjustment

The Multi Slide Depth Adjustment has increment

markings of 1/8" (3,2 mm). These markings are for

reference only in identifying the depth of your desired

cut. The multiple channels of the depth adjustment let

you choose the orientation of the attachment to the

tool. Be sure to securely tighten the screw within one

of the multiple channel positions.

To set cutting depth:

Cleaning Grout:

Do not remove grout more than 1/8" below the face

surface of the tile. Adjust the Multi Slide Depth

Adjustment and bit so that no more than 1/8" of the

bit extends beyond the base of the attachment.

After removing 1/8" of grout, regrout to tile level. Seal

the new grout.

Removing Grout to Replace A Broken Tile:

Remove all of the grout surrounding the broken tile.

Adjust the Multi Slide Depth Adjustment so that no

more than 1/8" of the bit extends beyond the base of

the attachment. See Figure 5. Remove grout at a

depth no more than 1/8" at a time. You may need to

adjust the Multi Slide Depth Adjustment by 1/8"

increments (reference the 1/8" incremental white

markings on the Multi Slide Depth Adjustment) and

make several passes until all the grout is removed.

When removing grout deeper into the grout line, you

may strike hidden objects like screw heads, mortar,

tile cement or nails that may cause the bit to bind,

overheat or break. Reduce the tool speed and work

through it slowly, making several passes. In case of

screws or nails, remove the grout around the area as

the bit will not cut through them.

Operating Instructions

Always pull the tool toward you!

Do not push it! Pushing the bit

may cause it to break. Hold the tool in a golf grip

with the tool positioned below the attachment and the

bit pointing upwards.

On your variable speed tool, recommended tool speed

is 15,000-20,000 RPM's or speed setting 6 to avoid

damage to the bit. On your two speed tool,

recommended tool speed is "Low" to avoid damage to

the bit. Do not force the bit or put pressure on the

back of the tool to remove the grout. Let the speed of

the rotating bit do the work.

Wear eye protection and dust

mask. Inspect bit for damage.

When bit is installed, always run it at no-load speed

of the tool for one minute, as a damaged bit will

break apart. Do not stand in front of or in line with

bit.

Always use the tool with the depth guide positioned

flat against the material being cut.

The guide securely positioned on the material

improves stability and control of your tool.

The direction of feed with the bit into the grout is

important. Always drag or pull the bit through the

grout line. The grout bit is not intended for "plowing"

through the grout and feeding the tool in the wrong

direction will cause the bit to climb out of the work

possibly damaging the bit and/or causing loss of

control.

Right Angle Attachment 575

Before you begin, remove the black protective cap on

your attachment. If cap does not slide off easily, insert

the shank portion of any accessory through the

housing opening of the attachment to hold shaft from

rotating. Then twist off. Figure 1.

Do not use the rotary tool shaft

lock button when changing

accessories on the attachment. Internal damage to

the attachment may occur.

Remove the housing cap from your existing rotary

tool as shown in fig. 2. Then press the shaft lock

button on your rotary tool, unscrew the collet nut and

remove the collet.

Set your collet nut and collet aside it will be

reinstalled later in step 4.

Install the drive adapter, included with your right

angle attachment, on the motor shaft as shown in

fig.3 and tighten.

Do not over tighten drive

adapter. Tighten the drive adapter

finger tight and then tighten an additional 1/3 turn

with the wrench. (Wrench included with your rotary

tool kit)

Screw the attachment onto your rotary tool. Hand

tighten only. Reassemble the collet and the collet nut

from step 2, on to the output shaft of the attachment.

Figure 4.

The right angle attachment can be oriented on your

rotary tool in 12 different positions. The attachment

should be positioned so the on/off speed control

switch is easy to access.

To reposition, unscrew the collar from the attachment

until disengaged. Slide the attachment off. Then,

reposition, slide the attachment back on the tool and

retighten the collar. Figure 5.

To change an accessory, insert the shank portion of

any accessory (3,2 mm recommended) through the

housing opening of the attachment to hold the shaft

from rotating. With the shaft secured, loosen the

collet nut and insert an accessory as deeply as

possible to avoid wobble during use. You may need to

pull back the shank from the housing opening to

provide clearance while inserting the accessory.

Service

Preventive maintenance per-

formed by unauthorized personnel

may result in misplacing of internal wires and

components which could cause serious hazard. We

recommend that all tool service be performed by a

Dremel Service Facility.

CARBON BRUSHES

The brushes and commutator in your tool have been

engineered for many hours of dependable service. In

order to prepare your brushes for use, run your tool at

full speed for 5 minutes under no load. This will properly

“seat” your brushes, which extends the life of both your

brushes and your tool. To maintain peak efficiency of the

motor, we recommend every 50 - 60 hours the brushes

be examined. Only genuine Dremel replacement brushes

specially designed for your tool should be used.

MAINTENANCE OF REPLACEABLE BRUSHES

ON MODELS 275T6, 285T6, & 395T6

The brushes should be inspected frequently when tools

are used continuously. If your tool runs sporadically,

loses power, makes unusual noises or runs at a

reduced speed, check the brushes. To continue using

the tool in this condition will permanently damage your

tool.

With the cord unplugged, remove the brush caps one

at a time with a small screwdriver by rotating cap

counter-clockwise and check each brush.

If the brush is less than 1/8" long and the end surface

of the brush that contacts the commutator is rough

and/or pitted, they should be replaced. Check both

brushes. Usually the brushes will not wear out simul-

taneously. If one brush is worn out, replace both

brushes. Make sure the brushes are installed as illus-

trated. The curved surface of the brush must match the

curvature of the commutator.

After replacing brushes the tool should be run at no-

load; place it on a clean surface and run it freely at full

speed for 5 minutes before loading (or using) the tool.

This will allow the brushes to “seat” properly and will

give you more hours of life from each set of brushes.

This will also extend the total life of your tool since the

commutator surface will “wear” longer.

BEARINGS

Models 275T6, 285T6, and 395T6 have double ball

bearing construction. Under normal use they will not

require lubrication.

Cleaning

To avoid accidents always dis-

connect the tool from the power

supply before cleaning or performing any main-

tenance. The tool may be cleaned most effectively with

compressed dry air. Always wear safety goggles when

cleaning tools with compressed air.

Ventilation openings and switch levers must be kept

clean and free of foreign matter. Do not attempt to clean

by inserting pointed objects through openings.

Certain cleaning agents and

solvents damage plastic parts.

Some of these are: gasoline, carbon tetrachloride, chlo-

rinated cleaning solvents, ammonia and household

detergents that contain ammonia.

Extension Cords

If an extension cord is necessary, a cord with

adequate size conductors that is capable of carrying

the current necessary for your tool must be used.

This will prevent excessive voltage drop, loss of

power or overheating. Grounded tools must use 3-

wire extension cords that have 3-prong plugs and

receptacles.

RECOMMENDED SIZES OF EXTENSION CORDS

120 VOLT ALTERNATING CURRENT TOOLS

NOTE: The smaller the gauge number, the heavier the

cord.

Dremel Accessories

The number and variety of accessories for the Rotary

Tool are almost limitless. There is a category suited to

almost any job you might have to do — and a variety of

sizes and shapes within each category which enables

you to get the perfect accessory for every need.

Refer to the DREMEL ACCESSORY ORDER FORM for

illustrations of the accessories available. These

accessories may be found at your local hardware,

hobby or home center dealers.

Collets

If you expect to use a variety of accessories, we

recommend that in the beginning you purchase a

complete set of four collets. Store these so that you will

have the proper size of collet for any accessory or drill

bit you want to use. Currently, the 1/8", 3/32",1/32"

and 1/16" collets accommodate all of the available

Dremel accessories. 1/8" collets are included in most

rotary tool kits.

Mandrels

A mandrel is a shank with a threaded or screw head,

which are required when you use polishing

accessories, cutting wheels, sanding discs, and polish-

ing points. The reason mandrels are used is that

sanding discs, cutting wheels and similar accessories

must be replaced frequently. The mandrel is a per-

manent shank, allowing you to replace only the worn

head when necessary, thus saving the expense of

replacing the shaft each time.

Screw Mandrel No. 401

This is a screw mandrel used with the felt polishing tip

and felt polishing wheels. 1/8" shank.

Small Screw Mandrel No. 402

This is a mandrel with a small screw at its tip, and is

used with emery and fiberglass cutting wheels, sanding

discs and polishing wheels. 1/8" shank.

Threaded Tip Mandrel No. 424

This is a mandrel with a threaded tip which threads into

the polishing point accessory No. 427. 1/8" shank.

High Speed Cutters

Available in many shapes, high speed cutters are used

in carving, cutting and slotting in wood, plastics and

soft metals such as aluminum, copper and brass. These

are the accessories to use for freehand routing or

carving in wood or plastic, and for precision cutting.

Made of high quality steel. 1/8" shank.

Tungsten Carbide Cutters

These are tough, long-lived cutters for use on hardened

steel, fired ceramics and other very hard materials.

They can be used for engraving on tools and garden

equipment. 1/8" shanks.

Engraving Cutters

This group has a wide variety of sizes and shapes, and

are made for intricate work on ceramics (greenware),

wood carvings, jewelry and scrimshaw. They often are

used in making complicated printed circuit boards.

They should not be used on steel and other very hard

materials but are excellent on wood, plastic and soft

metals. 3/32" shank.

Structured Tooth

Tungsten Carbide Cutters

Fast cutting, needle-sharp teeth for greater material

removal with minimum loading. Use on fiberglass,

wood, plastic, epoxy and rubber. 1/8" and 1/4" shank.

Aluminum Oxide Grinding Stones (red/brown)

Round, pointed, flat — you name the shape and there is

one available in this category. These are made of

aluminum oxide and cover virtually every possible kind

of grinding application. Use them for sharpening lawn

mower blades, screwdriver tips, knives, scissors, chisels

and other cutting tools. Use to remove flash from metal

castings, deburring any metal after cutting, smoothing

welded joints, grinding off rivets and removing rust.

These grinding stones can be resharped with a dressing

stone. In machine shops, high speed drills and cutters

normally are ground with aluminum oxide wheels. 1/8"

shank.

Silicon Carbide Grinding Stones (blue/green)

Tougher than aluminum oxide points, these are made

especially for use on hard materials such as glass and

ceramics. Typical uses might be the removal of stilt

marks and excess glaze on ceramics and engraving on

glass. 1/8" shank.
